IMPROVEMENT IN GRA-res.

Specification formingpart of Letters Patent No. 158,556, dated January5, 1875;- application tiled December 11, 1874.

The object of my'invention is to improvethe presentstyle of basketcoal-grates, by

- adjustable means, as Well as for dumping purposes; and to this end thegrate can be raised or lowered to regulate thedraft, according to thedepth of the fireplace, and, by turning the grate on its axes, toregulate the deflecting heat, Sto., all by means to be hereinafterdescribed.

In the drawings, Figure 1 is a side eleva tion ofmy'improvedbasket-grate for fuel, the dotted lines showing it in an inclinedposition to increase the quantity ot' deiiected heat, as also in shakingit, forboth of which purposes the handles a are used,and the shape ofthese can be varied at pleasure without departing from the nature of myinvention.

` A is` the basket-grate. b is the front tilting or pivoteddumping-plate with bars; c the" back or sliding plate, which can be sliddown or raised up, the sliding down being for the y purpose ot' coveringthe horizontal bottom bars d, (see Fig. 2,) to. regulate bottom draft. boscillates on trunnions e, by means of which to open it for dumpingpurposes; and, when closed, it is held in position at the top by abutton, j', bearing against e, while at the bottom projecting lugs restin grooves g in the side plates. B are standards or supporting`- legs onwhich the grate rests. They are slotted, each having two slots, g and h,the former having rests for supporting-trunnions e', attached to sidesof grate. These rests are to regulate the height of the basket, which isheld in any desirable position by means ot' a binding screw-nut, p, on arod or projection passing through slot It but this slot may be idispensed with, and'the screw-nut put cn projecting trunnions t'. Bymeans of the handles a the basket can be-raised or lowered, as well vasshaken or tilted.

screw-rods, &c., so that, it' desirable, the basket-grate can be takenapart easily for transportation.

For particular safety 'the grate can be tilted at night, or at any time,into a so-called horizontal position Fig. 3, Sheet 3, representsamodiiication of my invention. It has no adjustability save the slidingup or down ot' the front and back plates. The side plates can be maderemovable or Xed, and horizontal strengthening-bars may connect the sideplates, either xed or removable. It will readily be seen by this tigurethe dumping facilities are doubled, though not considered necessary.

I claim as my invention- 1. The combination of the slotted toothed legsB and the thumb-screw p, with the basket-grate A, enabling the grate tobe raised, lowered, or tilted, as andt'orthe purpose specilied.

2. The curved sliding back plate c, in combination with the side platesof basket-grate A, and its bottom bars d, for purposes ,hereindescribed.

3. The dumping axial bar-grate b, in combination with the slotted sideplates of basket A, and locking-button p, as and for the purpose setforth.
